Firewall: Theme Party Savoir-Faire

A man stops at an ATM and suddenly falls dead to the ground. A blackout cuts power to a large swath of southern Sweden. When a serviceman arrives at the malfunctioning power substation, he makes a grisly discovery. Inspector Kurt Wallander begins to sense a connection between all of these events and, at the same time, becomes increasingly aware of the vulnerability of a digitized society.
